Istif: Stack the Tower

How high can you stack? Tap at the right moment, line up the blocks, and watch your tower rise — one satisfying drop at a time.

Istif (Turkish for "stacking things up neatly") is built around a single rule: perfect timing wins. Anyone can pick it up in seconds, but beating your best takes real focus.

HOW TO PLAY
- Tap anywhere to drop the moving block
- Line it up with the block below to keep your tower solid
- Miss the edge and the overhang gets sliced off — your tower gets narrower
- Land a PERFECT drop to keep the full width
- Chain 3 or more perfect drops in a row and your block grows back wider!

WHY YOU'LL LIKE IT
- Perfect streaks let you rescue a shrinking tower — every run has a comeback
- Colors shift as your tower rises, so every run looks a little different
- One-tap controls, short rounds — perfect for a quick break
- Missed a block? Get a second chance with an optional short ad, once per run
- Your best score is always saved, so there's always something to chase
- Share your best runs with friends and see who climbs higher

Simple to learn, tough to master. Open Istif and see how high your tower can go.
